Embodiments of the present invention disclose a method, computer program product, and system for reducing network traffic. In one embodiment, a computer determines that a webpage has changed and that an amount of data to be transmitted to update the portion of the webpage that has changed is smaller than an amount of data to be transmitted to update the entire webpage.

Optimize data exchange for MVC-based web applications

A method and system are provided for debugging a software application in a data processing system that includes a server entity and client entities. For at least one of the client entities, a server component of the application running on the server entity is accessed, and a client component of the application is downloaded from the server entity. The client component is executed. Client log information relating to the execution of the client component is saved by invoking a log function provided by the client component; the client log information is saved into a non-persistent memory structure of the client component. The client log information is transmitted for use in the debugging of the application.

Method, system and computer program for debugging software applications in a web environment

A solution is proposed for reducing the response time of query submitted by a client to server and, at the same time optimizing the sorting time of the results. Some canonical sorting algorithms are conceived to produce the first sorted records as soon as possible even if the sort operation is not completed. Even if such kind of algorithms match the above described needs, they could become impracticable because of their computational complexity. On the other side, some other algorithms have a lower computational complexity but the sorted result can be available only after the last iteration when the algorithm has completed. The present invention provides an improved method which combines the advantages of both families of algorithms.

Sorting tables in a page based approach

A method () and system () for transmitting information across a firewall () between multiple endpoints () and gateways (), in a resource management environment (such as the TME) having characteristics that are firewall-incompatible. A gateway proxy () and an endpoint proxy () are associated with the endpoints and the gateways, respectively. The two proxies are connected to each other by means of a pass through communication tunnel crossing the firewall, which tunnel is secured by mutual authentication of the gateway proxy and the endpoint proxy at its ends. Each endpoint and each gateway is tricked into communication only with the respective proxy. Particularly, a listening port is allocated on the endpoint proxy on behalf of each endpoint, so that the corresponding gateway will open a connection back to the endpoint proxy on the listening port for transmitting any packet to the endpoint. A table () stored on the endpoint proxy associates each listening port with the corresponding endpoint for managing the routing of the packets.

Method and system for transmitting information across a firewall

A mechanism provides a layered communication stack. A connection manager manages the actual transfer of data through a single point-to-point connection crossing a respective firewall. A sessions manager multiplexes multiple sessions over the connection. A routing manager exploits the sessions manager for building a routing table dynamically. A routed sessions manager implements routed sessions between two applications at opposite ends of the system; the routed sessions manager exploits the sessions manager to let the data navigate through the firewalls, and it exploits the routing manager to address the data correctly from source to destination.

Transmitting information across firewalls

A solution is proposed for reducing the response time of a long query submitted by a client () to a server ()&#x2014;storing a corresponding database (). For this purpose, when the server receives the query from the client it starts collecting the result of the query into a table (), wherein the corresponding selected records are directly accessible at page level (to the contrary of the database). As soon as a first page (Pg) of the selected records is available in the table, the page is transmitted to the client for its display. Meanwhile, in a completely asynchronous manner, the server continues populating the table. Later on, the user of the client submits a browsing command to the server for moving to a different page (Pgk). In response thereto, the server extracts this page from the table (as soon as available) and returns it to the client directly.
